https://2019.za.pycon.org/talks/64-anomaly-detection-using-autoencoders/ Finding anomalous behaviour can be similar to finding a needle in a haystack. This information can be very useful for fraud detection or identifying unusual behavior. Machine Learning techniques such as autoencoders can assist in this process. We will present a jupyter notebook followed by a visualisation which indicates anomalous activity using an open source credit card dataset. The anomalous activity will be compared to...

https://2019.za.pycon.org/talks/4-talk-data-to-me-the-art-of-storytelling/ Collecting data is now seen as a very important aspect of business. Many companies therefore invest in solutions such as Business Intelligence tools, spreadsheets and dashboards in an attempt to extract useful information from their data. However, these tools still fail to present what is hidden in the data because they do not bring out their underlying significance. This is where data storytelling comes in. It helps to...

https://2019.za.pycon.org/talks/80-getting-machine-learning-models-ready-for-production-using-python/ As a Scientist, it’s incredibly satisfying to be given the freedom to experiment by applying new research and rapidly prototyping. This satisfaction can be sustained quite well in a lab environment but can diminish quickly in a corporate environment. This is because of the underlying commercial value motive which science is driven by in a business setting — if it doesn’t add business...

In this talk I’ll try to answer these questions and explain how type annotations helped my team scale, made our code more efficient and new hires happier.
